137438-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 137438-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,3 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.Calculate Digit Verification of CAS Registry Number 137438-28:
(8*1)+(7*3)+(6*7)+(5*4)+(4*3)+(3*8)+(2*2)+(1*8)=139
139 % 10 = 9
So 137438-28-9 is a valid CAS Registry Number.
